The following was received by the State of Illinois via email:
"The Radiation Safety Officer (RSO) at Equistar Chemical notified the Agency [Illinois Emergency Management Agency] via email that while performing routine shutter tests of fixed gauges at their Morris, IL location, it became known that for one of the gauges, a shutter was stuck in the 'open' position. The affected Ohmart Vega model SH-F2 gauge contains 300 milliCi of Cs-137 and is mounted on a reactor vessel within a secure area at the plant. The associated process line for the vessel does not have any maintenance scheduled to occur until next year, therefore, no entry into the vessel should be necessary and the gauge is expected to remain in the 'on' position due to operational need. The gauge manufacturer has been contacted and advised of the situation. Equistar and Vega Americans are currently attempting to schedule a field service engineer to come on site to investigate the matter and make necessary repairs/replacement. The licensee has previous experience with events of this type due to the large number of devices in use and the stressful environment that exists at this site. The licensee is prepared to respond to any further deterioration that, although not likely, may occur. Plant personnel have been advised of the matter and the process line supervisors have been instructed to contact the RSO should any abnormal events associated with the reactor processes becomes known. No on-site investigation is planned by the Agency at this time."

The following report was received from the California Department of Public Health via email:
"On September 23, 2016, the Radiation Safety Officer of the University of California, Los Angeles (UCLA), contacted the Brea office of the Radiologic Health Branch to report a medical event.
"A patient was treated with Nordion TheraSpheres containing yttrium-90 (Y-90) on September 22, 2016. The prescribed dose was 100 gray (Gy) to the left lobe of the liver. Upon completing the dose assessment after the treatment, it was discovered that only approximately 50 percent of the intended dosage of Y-90 was delivered to the patient (left lobe of the liver). The remainder of the Y-90 dosage appears to have remained in the delivery system, primarily in the system waste container. The licensee performed surveys to confirm that the areas surrounding the delivery system and patient were not contaminated.
"The patient has been notified, and the licensee is investigating to determine the cause of the event."

The following information was provided by the State of Arkansas via email:
"On September 23, 2016 at 1300 CDT, the licensee contacted the Department [Arkansas Department of Health] reporting that during operations on September 22, 2016, the licensee discovered that the shutter on a Vega Americas Model BAL density gauge would not open. The gauge contains 300 milliCuries of Krypton-85.
"The gauge was replaced with a spare gauge and has been placed in a secure storage area and radiation exposure is maintained at less than 2 mR/hr.
"The licensee is contacting the manufacturer to request repair or disposal of the gauge.
"In accordance with RH-1502.f.2 (10 CFR 30.50(b)(2)) the malfunctioning shutter is reportable within 24 hours.
"The State of Arkansas is awaiting a written report from the licensee. The State's event number is AR-2016-011." |

"On October 2, 2016 during the Braidwood Station Unit Refueling outage (A1R19), an in-service Liquid Penetration examination was performed on the previously repaired control rod drive mechanism (CRDM) penetration 69. During the examination on the weld build up for CRDM penetration 69, two indications were discovered. A 7/32 inch rounded indication was discovered located at 359 degrees on the reactor head portion of the weld buildup, and it is 4 inches from the transition of the head to penetration. A 1/4 inch rounded indication was also discovered located at 200 degrees at the transition of the head to penetration. 0 degrees is located at the outermost portion of the penetration on the flange side. The transition is the point where the vertical portion of the penetration meets the horizontal area of the reactor head.
"Rounded indications that exceed 3/16 inch are rejectable per ASME Code Case N-729-1.
"This is reportable pursuant to 10CFR50.72(b)(3)(ii)(A), 'Any event or condition that results in the condition of the nuclear power plant, including its principal safety barriers, being seriously degraded' since the as found indication did not meet the applicable acceptance criteria referenced in ASME Code Case N-729-1 to remain in-service without repair.
"The NRC Resident Inspector has been informed." |

"On October 3, 2016, at 1008 PDT a Reactor Building Exhaust Valve (REA-V-1) unexpectedly closed, which caused the Technical Specification (TS) for secondary containment pressure boundary to not be met. The duration of time that the secondary containment TS was not met was approximately 4 minutes.
"Secondary containment differential pressure was restored within TS requirement of greater than or equal to 0.25 inches of vacuum water gauge at approximately 1012 PDT by manually starting Standby Gas Treatment (SGT) system (SYS) A. The cause of the REA-V-1 closure is currently under investigation.
"This condition is being reported under 10CFR50.72(b)(3)(v)(C) for an event or condition that could have prevented fulfillment of a safety function needed to control the release of radioactive material.
"The licensee has notified the NRC Resident Inspector." | |
